This invention relates totoys and more adapted to be .used in connection with a third rail electric track equipment. 7 1

The invention especially relates to electric lighting means for cars and locomotives of the above class and has for its object im- 1 proved means, for receiving and supporting an electric lamp socket within a car, which can be carried into effect without the necessity of resorting to the heretofore expensive operation of soldering these sockets in position in the car body;

A further feature of the invention is to provide a simple and eliicient means of detachably securing the socket in position in a manner which will allow the socket to be quickly removed and another replaced, should it become necessary.

Still another object ofthe invention is to design the improved socket fastening means,

so that the same may be carried into efiect and applied to existing structures of a toy car body and without the necessity of additional or foreign parts.

lVith the foregoing and other objects in view, which will appear, as the description proceeds, the invention resides in the com-. bination and arrangement of parts and 111' the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of themvention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings a preferred form of the invention has been shown as applied to an electric toy passenger car, though, as previously suggested, the same may be applied to a locomotive with the same effect and advantage.

In the drawings Fig. 1 shows a central vertical longitudinal section of a sheet metal toy electric passenger car, mounted upon a rail, and to which my invention is shown applied;

Fig. 2 shows a central vertical cross-sec.- tion through the car body taken on-line 22 of Fig. 1;

Fig. 3 is a further sectional view through the car body taken on line 33 of Fig. 1,

better to illustrate'the socket positioned in I the end portion of the car; 7

Fig. 4 shows a detached bottom plan view of 'acar brace employed inside the upper intermediate portion of the car body as shown in Fig. 1-, and to which the lamp socket may be secured by my improved means; and

F ig.- 5 is asimilar detached bottom plan view. of the brace, with a lamp socket secured therein.

In the accompanying drawings, I have shown the invention in connection With a screw form of lamp socket, of the smaller type, but the invention need not be confined ard Edison base lamp and also lamps employing bayonet socket connections.

Referring in detail to the characters of reference marked upon the drawings, 10 represents a rail forming a part of the track upon which-cars of this type are adapted to operate. 11-11 indicate trucks for supporting the car 12, which car and trucks are swivelly connected as at 13. The car may obviously be of' any desired construction since I the invention is not limited in this respect and is alsoadapted to be used in cabs oftoy locomotives. 'Most of the larger and more substantially constructed types of electric cars employ a form of cross-brace in the upper portion of the body to stiffen and strengthen the structure, such as is shown in the drawings and indicated as 14. These braces are made of a single strip of metal having their side edges 15 disposed-downward at a right angle to form reenforcements and are provided with turnedup ears 1616 upon opposite end portions which are passed through slots 17 of the inturned flanges 18 of the'carbody for the attachment of the brace to and within the car body, the said ears being. turned over and down as shown in Figs. 1 and2 to provide. a rigid connecof the car where the lamp is to be positioned and deflecting the opposite edge portions 20 of the hole so formed inopposite directions to form a spiral thread into which the threads of a lamp socket 21 may be turned, in a way to receive and support the socket in the man ner shown. The socket "thus projects from the brace at a right angle leaving the hollowed portion of the socket which receives thela-mp open on the'under side of the brace and in position to receive a lamp. Lugs 22-22 are also formed of the brace plate at opposite sides of the hole 19 preferably by stamping the same out from thestock and disposing them downward at a right angle, as in- Fig. 4, so that, as the socket is screwed in to the hole ot' the brace member, and the flange 23 of the socketseated against the face of the edge portion of the hole, the said lugs are then turned down upon the said flange as shown in Fig. 5.- and swedged, in a way. to securely hold the socket in position.- If the removal of the socket becomes necessary for repairs or otherwise, it may be quickly taken out by turning the said lugs 22 back off of the flange of the socket in a way to free the same and-permit it to be turnedout of the hole in i the car member. 1

- The application of the invention to the end portions of a car may be effected in the same 1 manner as is shown applied tothe cross-brace.

In this connectionit maybe of interest to note form a broken thread, and a threaded lamp socket seated in said hole, said-lugs being bent back upon the socket to hold it in place.
